MIXING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 472,092, dated April 5,1892.

Application filed April 8, 1891. Serial No. 388,160%- (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM BRUMMEL WHEELER, a citizen of the UnitedStates, residing at the city of Madison, in the county of Dane and Stateof WVisconsin, have invented a new and useful Paint or Liquid Agitatingor Mixing Machine, of which the following is a specification.

My invention relates to improvements in paint or liquid agitating ormixing machines, in which vertical rotating shafts journaled at the topand bottom ends are provided with horizontally-projecting arms orpaddles; and the objects of my improvement are, first, to scrape anyhard substance or sediment from the bottom of a barrel or tank and by acontinuous action of currents and counter-currents to thoroughly mix itwith a liquid; second, to agitate a liquid so as to facilitate itsmixing with another substance, and, third, to be able to readily changethe machine from one barrel or cask to another. I attain these objectsby the mechanism illustrated in the accompanying drawings, in which-Figure 1 is a left side view of the entire machine fitted to a barrelwhich is shown in section; Fig. 2, a plan of spider or upper frame ofmachine; Fig. 3, a side View of vertical shaft, showing ends of paddles;Fig. 4, a plan of gear h, showing square hole in center; Fig. 5, avertical section of step and lower end of vertical shaft; Fig. 6, asection through line A B, Fi 2.

Similar letters refer to similar parts throughout the several views.

a is a socket or step provided with three or more downwardly-projectingpoints 5, which are to be driven into the bottom of barrel or tank '0,to which my machine. is applied and which forms the lower bearing forvertical shaft 0, directly above which bearing on vertical shaft are twoconcave double edged scrapers or horizontally-projecting arm's cl, thatbytheir lower edges,which are also their front edges, rotating in eitherdirection, passing near the floor or bottom of barrel 0,-remove and givean upward motion to any sediment or hard substance that may collectthereon. A little distance above the scrapers d is a pair of paddles e,whose upper and lower edges are cut into notches f, and along theirhorizontal center line is a number of square holes g, (three in thisinstance.) This pair of paddles is set at such an angle that by therotating of vertical shaft 0 the upward current caused by the scrapers01 will be reversed, excepting what material may pass through the holes9 and otherwise escape their action. Next above paddles e is a pair ofpaddles e similar to or may be identically the same in construction, butwhich are set on vertical shaft at an angle opposite, so as to reversethe current formed by paddles e, and by this arrangement of a sufficientnumber of paddles I am able to thoroughly agitate and mix the materialdesired.

Some distance above the upper or last pair of paddles the vertical shaft0 is made square, so as to engage the gear h by passing through thesquare hole h in its center, as before described. The top of shaft 0 isround and fitted to a bearing or box r in bracket 2. Said bracket 'i'isprovided with two bearings 19 19, connected bya rib q, and directlyunder bearings 10 p are lugs s s, which are bolted to corresponding lugst t,which are a part of spider u. Through and fitted to the bearings 1919 passes a shaft m, to the front or inner end of which is fastened agear Z,which engages gear h, and upon its outer end is a crank or handlen, (in this instance,) but to which may be fastened any device for thepurpose of conducting or transmitting power thereto.

The spider a has a central hub to, having a hole passing verticallythrough it, forming a bearing for the hub on lower side of gear h, andhaving three horizontalarms spaced equidistant passing to and a littlebeyond the edge of barrel or tank to which it is intended to befastened. Said arms are turned down a sufficient distance to admit ofpassing a set-screw j through them near their points for the purpose offastening them securely to barrel. One of these arms 1: is adjustable inregard to length by means of the thumb-screw lawhich passes through thearm n and engages with a nut 20 in slot 00 in lower arm 1;.

The step a is fastened to lower end of vertical shaft 0 by a washer abeing riveted to shaft, as shown in Fig. 5, so that the machine may beapplied to a barrel of mixed paint by first putting vertical shaft 0,with step a attached, into barrel and by blows on top of shaft seatingor driving points b into bottom,

then placing spider u, with its attachments, in position on top ofbarrel, and turning up set-screws j.

I am aware that prior to my invention paint and liquid agitating ormixing machines have been made, and therefore do not claim such amachine, broadly; but

What I do claim as my invention, and desire to secure by Letters Patent,is

The combination, in a paint-mixing ma- I0 chine, of a vertical shaft 0,journaied at top and bottom ends and carrying at lower end twodouble-edged concave scrapers (I, as described, and for purposes setforth.
